Compatibility with Official Arduino IDE, Software, Sendsors and Codes

Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board.

For the reason of open source, the manufacture of Arduino boards and software distribution by anyone is permitted. Arduino boards are available commercially in preassembled form, or as do-it-yourself (DIY) kits.

Elegoo is one of the manufacturer on the market, whose clone products are compatible with the official Arduinomicrocontroller boards, they can use the official Arduino software, sensors and codes.

Learn Electronics and Programming with ELEGOO

The UNO boards can be used as the brains behind almost any electronics project. UNO can interact with buttons, LEDs, motors, speakers, GPS units, cameras, the internet, and even your smart-phone or your TV! By connecting the UNO board with a personal computer via a USB cable and uploading programs to the board, users can create digital devices and interactive objects that can sense and control objects in the physical and digital world like robots or even honest fortune-telling machines.

For this Elegoo Super Starter Kit, we provide a 24-lesson tutorial, introducing the basic setting of the software IDE, the working principles of the sensors and the simple program to enable the UNO board to control the sensors.

This Kit is suitable for 10-year-old and up. Younger kids should be under supervision and guidance of adults.

74HC595 and LEDs

74HC595 is a Serial to Parallel Converter which has eight outputs (perfect) and three inputs that you use to feed data into it a bit at a time.

This chip makes it a little slower to drive the LEDs (you can only change the LEDs about 500,000 times a second instead of 8,000,000 a second) but it's still really fast, way faster than humans can detect, so it's worth it.

74HC595 shift register is a type of chip that holds what can be thought of as eight memory locations, each of which can either be a 1 or a 0. To set each of these values on or off, we feed in the data using the 'Data' and 'Clock' pins of the chip.

4 digit 7 segment display

7 segment displays consist of 7 LEDs, called segments, arranged in the shape of an “8”. Most 7-segment displays actually have 8 segments, with a dot on the right side of the digit that serves as a decimal point. When using 4-digit 7-segment display, the common anode or common cathode pin is used to control which digit is displayed. Even though there is only one digit working, the principle of Persistence of Vision enables you to see all numbers displayed because each the scanning speed is so fast that you hardly notice the intervals. By building the circuit and editing the program, users can make a simple display showing certain numbers, or more complexly, a count-up timer or a elecrical rolling dice.

Stepper Motor

Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called "phases". By energizing each phase in sequence, the motor will rotate, one step at a time.

With a computer controlled stepping you can achieve very precise positioning and/or speed control. For this reason, stepper motors are the motor of choice for many precision motion control applications.

the simplest way of interfacing a unipolar stepper motor to UNO board is to use a breakout

for ULN2003A transistor array chip, applying voltage to each of the coils in a specific sequence.

Product features

The Breadboard Power Supply has two power modes:

1) M/M USB Power Cable（included in this kit）;

2) 9V 1A DC Adapter（Not included in this kit）.

Jumper Wires

Jumper wires can be used for pin extension of the experiment board, adding experimental items, and the like. It can be connected very securely to the pins, eliminating the need for soldering and allowing quick circuit testing.

Our kit includes 65pcs male to male jumper wires, 20pcs male to female dupont wires, and 140pcs solderless jumper wires. which are completely adequate for various experiments.

IC 74HC595

The 74HC595 consists of an 8−bit shift register and a storage register with three−state parallel outputs. It converts serial input into parallel output so that you can save IO ports of an MCU. The 74HC595 is widely used to indicate multipath LEDs and drive multi-bit segment displays. "Three-state" refers to the fact that you can set the output pins as either high, low or "high impedance." With data latching, the instant output will not be affected during the shifting; with data output, you can cascade 74HC595s more easily.

IC 4N35

The 4N35 is a 4-terminal universal optocoupler that blocks the electrical connection between the signal source and the receiver of the signal, which effectively blocks electrical connections and interference. Commonly used in signal isolation transmission, switching power supply feedback control and so on. Common circuits include TV power supply parts (remote control switch, voltage feedback control), switching power supply, electric vehicle charger and many other aspects.

Buzzer

An active buzzer will generate a tone using an internal oscillator, so all that is needed is a DC voltage. A passive buzzer requires an AC signal to make a sound. It is like an electromagnetic speaker, where a changing input signal produces the sound, rather than producing a tone automatically.

To identify them, if you apply a DC voltage to them and it buzzes, it's an active.As far as commands go if you want to control the pitch, you would need a passive buzzer.

PN2222 NPN Transistor

The PN2222 can be used as a switch that use a little current from the R3 digital output to control the much bigger current of the motor. Because the small DC motor is use more power than an R3 digital output can handle directly.

1N4007 Diode

1N4007 Diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above. For 1N4007 Diode, the maximum current carrying capacity is 1A it withstand peaks up to 30A. Hence we can use this in circuits that are designed for less than 1A. The reverse current is 5uA which is negligible.

Electrolytic Capacitor

Electrolytic capacitor is a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. An electrolyte is a liquid or gel containing a high concentration of ions. Almost all electrolytic capacitors are polarized, which means that the voltage on the positive terminal must always be greater than the voltage on the negative terminal.

Ceramic Capacitor

Ceramic capacitor uses a ceramic material as the dielectric. Ceramics were one of the first materials to be used in the production of capacitors, as it was a known insulator. Ceramic capacitors are usually made with very small capacitance values. Ceramic capacitors are also very small in size and have a low maximum rated voltage. They are not polarized, which means that they may be safely connected to an AC source. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance.

Besides, we offer other over 60 kinds of components and sensors from small parts like LED diodes, resistors and potentiometer to big parts like LCD1602, RFID module and 830 tie-points breadboard, which meet your demands for your different projects either it is simple or complex.

Sturdy quality is definitely the most important thing to Elegoo even with so many components provided we never compromised on the quality. Instead we keep improving our product quality in our own factory and we produce the products by ourselves under high standards and strict quality control. Pins and wires on some of the parts like LCD16502 and motors have been pre-soldered which is very convenient and saves your time.

LCD1602 Display module

LCD1602 module is a display that has an LED backlight and can display two rows with up to 16 characters on each row. You can see the rectangles for each character on the display and the pixels that make up each character. The display is just white on blue and is intended for showing text.

Lining up the display with the top of the breadboard helps to identify its pins without too much counting, especially if the breadboard has its rows numbered with row 1 as the top row of the board. Do not forget, the long yellow lead that links the slider of the pot to pin 3 of the display. The 'pot' is used to control the contrast of the display.

DC Motors and L293D Transistor

In this project you will learn how to control a small DC motor using a Mega2560 board and a L293D transistor, which is a very useful chip. It can actually control two motors independently. We are just using half the chip in this lesson, most of the pins on the right hand side of the chip are for controlling a second motor.

L293D is quadruple high-current half-H drivers and designed to provide bidirectional drive currents of up to 1 A at voltages from 4.5 V to 36 V. The L293D is also designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V and drive inductive loads such as relays, solenoids, dc and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.

Product features

74HC595

At sometime or another you may run out of pins on your UNO board and need to extend it with shift registers. This example is based on the 74HC595. The datasheet refers to the 74HC595 as an "8-bit serial-in, serial or parallel-out shift register with output latches; 3-state." In other words, you can use it to control 8 outputs at a time while only taking up a few pins on your microcontroller. You can link multiple registers together to extend your output even more.

4N35

The 4N35 is an optocoupler for general purpose application. It consists of gallium arsenide infrared LED and a silicon NPN phototransistor. When the input signal is applied to the LED in the input terminal, the LED lights up. After receiving the light signal, the light receiver then converts it into electrical signal and outputs the signal directly or after amplifying it into a standard digital level. Thus, the transition and transmission of electricity-light-electricity is completed. Since light is the media of the transmission, meaning the input terminal and the output one are isolated electrically, this process is also be known as electrical isolation.

PN2222 NPN Transistor

The small DC motor, is likely to use more power than an UNO digital output can handle directly. If we tried to connect the motor straight to an UNO pin, there is a good chance that it could damage the UNO. A small transistor like the PN2222 can be used as a switch that uses just a little current from the UNO digital output to control the much bigger current of the motor. The transistor has three leads. Most of the electricity flows from the Collector to the Emitter, but this will only happen if a small amount is flowing into the Base connection. This small current is supplied by the UNO digital output.

Electrolytic Capacitor

An electrolytic capacitor is a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. An electrolyte is a liquid or gel containing a high concentration of ions. Almost all electrolytic capacitors are polarized, which means that the voltage on the positive terminal must always be greater than the voltage on the negative terminal. The benefit of large capacitance in electrolytic capacitors comes with several drawbacks as well. Among these drawbacks are large leakage currents, value tolerances, equivalent series resistance and a limited lifetime.

Ceramic Capacitor

A ceramic capacitor uses a ceramic material as the dielectric. Ceramics were one of the first materials to be used in the production of capacitors, as it was a known insulator. Ceramic capacitors are usually made with very small capacitance values. Ceramic capacitors are also very small in size and have a low maximum rated voltage. They are not polarized, which means that they may be safely connected to an AC source. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance.

A diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above. For 1N4007 Diode, the maximum current carrying capacity is 1A it withstand peaks up to 30A. Hence we can use this in circuits that are designed for less than 1A. The reverse current is 5uA which is negligible. The power dissipation of this diode is 3W. Applications of Diode: ● Can be used to prevent reverse polarity problem ● Half Wave and Full Wave rectifiers ● Used as a protection device ● Current flow regulators

User questions & answers

Question:	On the LEDs, which side is the anode and which side is the cathode
Answer:	Approximately 30” long without the extensions
Question:	Is the 9 volt power in jack a center positive, or center negative
Answer:	Dear sir, I am very sorry for the misunderstanding. Our product is 63CC post hole digger. We will introduce this product in as much detail as possible in the future. Please give us time thanks
Question:	What current are the jumper wires rated for
Answer:	It's a little heavy, but well made. I've dug alot of fence post holes with it. Only problem I've had is the handles can actually slam together at the top and smash your fingers unless you put a stop on them like I did.
Question:	how many amps is the power supply rated for
Answer:	Yes

Product features

The Breadboard Power Supply has two power modes:

1) M/M USB Power Cable（included in this kit）;

2) 9V 1A DC Adapter（Not included in this kit）.

Jumper Wires

Jumper wires can be used for pin extension of the experiment board, adding experimental items, and the like. It can be connected very securely to the pins, eliminating the need for soldering and allowing quick circuit testing.

Our kit includes 65pcs male to male jumper wires and 20pcs male to female dupont wires, which are completely adequate for various experiments.

74HC595

The 74HC595 consists of an 8−bit shift register and a storage register with three−state parallel outputs. It converts serial input into parallel output so that you can save IO ports of an MCU. The 74HC595 is widely used to indicate multipath LEDs and drive multi-bit segment displays. "Three-state" refers to the fact that you can set the output pins as either high, low or "high impedance." With data latching, the instant output will not be affected during the shifting; with data output, you can cascade 74HC595s more easily.

4N35

The 4N35 is a 4-terminal universal optocoupler that blocks the electrical connection between the signal source and the receiver of the signal, which effectively blocks electrical connections and interference. Commonly used in signal isolation transmission, switching power supply feedback control and so on. Common circuits include TV power supply parts (remote control switch, voltage feedback control), switching power supply, electric vehicle charger and many other aspects.

Buzzer

An active buzzer will generate a tone using an internal oscillator, so all that is needed is a DC voltage. A passive buzzer requires an AC signal to make a sound. It is like an electromagnetic speaker, where a changing input signal produces the sound, rather than producing a tone automatically.

To identify them, if you apply a DC voltage to them and it buzzes, it's an active.As far as commands go if you want to control the pitch, you would need a passive buzzer.

PN2222 NPN Transistor

The PN2222 can be used as a switch that use a little current from the R3 digital output to control the much bigger current of the motor. Because the small DC motor is use more power than an R3 digital output can handle directly.

1N4007 Diode

1N4007 Diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above. For 1N4007 Diode, the maximum current carrying capacity is 1A it withstand peaks up to 30A. Hence we can use this in circuits that are designed for less than 1A. The reverse current is 5uA which is negligible.

Electrolytic Capacitor

Electrolytic capacitor is a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. An electrolyte is a liquid or gel containing a high concentration of ions. Almost all electrolytic capacitors are polarized, which means that the voltage on the positive terminal must always be greater than the voltage on the negative terminal.

Ceramic Capacitor

Ceramic capacitor uses a ceramic material as the dielectric. Ceramics were one of the first materials to be used in the production of capacitors, as it was a known insulator. Ceramic capacitors are usually made with very small capacitance values. Ceramic capacitors are also very small in size and have a low maximum rated voltage. They are not polarized, which means that they may be safely connected to an AC source. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance.

What about novice users who don't have any electronics knowledge? Fear not amigo. Just follow our tutorial enclosed and step by step you will come to realize that learning electronics is more fun than you ever expected with this amazing sensor kit.

It’s a good choice and perfect gift for your friends, family or kids who are obsessed with electronics, programming or robotics1 to take their first steps on electronics journey.

The most complete starter Kit with high quality components and sensors

Quantity and quality are both important here in Elegoo UNO R3 starter kit. The most essential parts in this kit are UNO R3 controller board and expansion board, which is a perfect clone with excellent product finish compatible with Arduino projects.

Besides, we offer other over 60 kinds of components and sensors from small parts like LED diodes, resistors and potentiometer to big parts like LCD1602, RFID module and 830 tie-points breadboard, which meet your demands for your different projects either it is simple or complex.

Sturdy quality is definitely the most important thing to Elegoo even with so many components provided we never compromised on the quality. Instead we keep improving our product quality in our own factory and we produce the products by ourselves under high standards and strict quality control. Pins and wires on some of the parts like LCD16502 and motors have been pre-soldered which is very convenient and saves your time.

74HC595 Shift Register and LEDs

74HC595 is a Serial to Parallel Converter which has eight outputs (perfect) and three inputs that you use to feed data into it a bit at a time.

This chip makes it a little slower to drive the LEDs (you can only change the LEDs about 500,000 times a second instead of 8,000,000 a second) but it's still really fast, way faster than humans can detect, so it's worth it.

74HC595 shift register is a type of chip that holds what can be thought of as eight memory locations, each of which can either be a 1 or a 0. To set each of these values on or off, we feed in the data using the 'Data' and 'Clock' pins of the chip.

LCD1602 Display module

LCD1602 module is a display that has an LED backlight and can display two rows with up to 16 characters on each row. You can see the rectangles for each character on the display and the pixels that make up each character. The display is just white on blue and is intended for showing text.

Lining up the display with the top of the breadboard helps to identify its pins without too much counting, especially if the breadboard has its rows numbered with row 1 as the top row of the board. Do not forget, the long yellow lead that links the slider of the pot to pin 3 of the display. The 'pot' is used to control the contrast of the display.

DC Motors and L293D Transistor

In this project you will learn how to control a small DC motor using an UNO R3 and a L293D transistor, which is a very useful chip. It can actually control two motors independently. We are just using half the chip in this lesson, most of the pins on the right hand side of the chip are for controlling a second motor.

L293D is quadruple high-current half-H drivers and designed to provide bidirectional drive currents of up to 1 A at voltages from 4.5 V to 36 V. The L293D is also designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V and drive inductive loads such as relays, solenoids, dc and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.

With this kit, we will walk you through the know-how of using the SunFounder board in a hands-on way. Starting with the basics of electronics, you'll learn through building several creative projects. Including many common but useful electronic components as well as an LCD1602 module, this kit will help you "control" the physical world in a "visible" way.

74HC595

At sometime or another you may run out of pins on your board for Arduino and need to extend it with shift registers. This example is based on the 74HC595. The datasheet refers to the 74HC595 as an "8-bit serial-in, serial or parallel-out shift register with output latches; 3-state." In other words, you can use it to control 8 outputs at a time while only taking up a few pins on your microcontroller. You can link multiple registers together to extend your output even more.

4N35

The 4N35 is a 4-terminal universal optocoupler that blocks the electrical connection between the signal source and the receiver of the signal, which effectively blocks electrical connections and interference. Commonly used in signal isolation transmission, switching power supply feedback control and so on. Common circuits include TV power supply parts (remote control switch, voltage feedback control), switching power supply, electric vehicle charger and many other aspects.

1N4007

1N4007 Diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above. For 1N4007 Diode, the maximum current carrying capacity is 1A it withstand peaks up to 30A. Hence we can use this in circuits that are designed for less than 1A. The reverse current is 5uA which is negligible.

User questions & answers

Question:	Does this contain a rely
Answer:	I needed to solder my RFID/NFC module. The pins did not come pre soldered.Everything else was fine though.
Question:	New to this. All i need is this a computer and a sodering iron
Answer:	The unit I recieved functions identically to the Arduino.Same chip. All Arduino library sketches run fine on it.I was very very pleased with this kit. I highly recommend it.
Question:	What are the power output specs on the output pins and the 5V/ground pins? Are the power requirements identical to the Arduino Uno boards
Answer:	LED stands for light-emitting diode, which means that much like their diode cousins, they're polarized. There are a handful of identifiers for finding the positive and negative pins on an LED. You can try to find the longer leg, which should indicate the positive, anode pin. Or, if someone's trimmed the legs, try finding the flat edge on the LED's outer casing. The pin nearest the flat edge will be the negative, cathode pin.
Question:	Does this include the arduino board also or is this just the breadboard
Answer:	The 9v power must be used with a DC 2.o plug.

User questions & answers

Question:	what is the spacing of the holes in the breadboard? 0.10" or 2.0mm
Answer:	I measured the boards I received, and the holes do NOT appear to be on 0.10" centers. I don't know what they are. They don't line up with 0.10" solder protoboards I have.
Question:	Does the black ink that shows column letters and row numbers smudge or rub off easily
Answer:	No, the ink seems to be pretty permanent. At least so far :)
Question:	can the power bus be removed from the rest of the breadboard
Answer:	Yes, both sides can be removed although cutting through the adhesive backing and adhesive can be a bit of a pain. You also have to remember to clear the space where the "ears" are so they slide apart easily.
Question:	Is the thru hole spacing sized for standard DIP packages
Answer:	Yes.
Question:	Does it matter that the caps in my tv are blue amd not black
Answer:	shouldn't matter as long as capacity (uF) is the same and the voltage (V) is >= to the caps you have. I think this brand is supposed to be pretty good quality.
Question:	So how do you use the then i do have a tv that is kind of broken that i could use them for but i thought i was buying them for a capacitor for my car
Answer:	This item are standard capacitors, not super/ultra capacitors. My use case was to solder all these capacitors together to smooth out the 12 volt output from my rectified landscape lighting style power transformer I use for my refrigerators (12/24 volt RV/sleeper truck compressor type). If you have a power source that you feel doesn't give you smooth enough DC electricity, splice these into the circuit and off you go. Just don't exceed the 25 volt rating, or you'll have some firecrackers instead.
Question:	Can i use this cap for dc volt
Answer:	Electrolyte capacitor are designed to be use only in D.C., if it get connected to A. C. it will burst open.
Question:	Can you tell me how tall they are
Answer:	13x20mm/0.51x0.79 inch
